To all whom z'tvmay concern.'

Be it known that I, .EDWIN E. SLICK, a citizen of the United States, 'residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Vehicle Wheels, of which the following is a full, clear, and exact description, *reference being had to the accompanying drawin s, forming part of this specification, in w ich Figure 1 is 'a side elevation of a vehicle wheel embodying the invention. 4

The present invention relates to vehicle wheels and more particularly to a vehicle wheel in which a corrugated disk joins the hub and the rim. The invention also re` lates to an improved means for demountably securing a tire rim to a vehicle wheel.

The object of the invention is to produce a strong, li ht and simple vehicle wheel and, with this o ject in view, the invention consists inthe combination and arrangement of parts hereinafter described. and more particularly pointed out in the claims, the advantages of which will be apparent to one skilled in this art from .the following description.

edge o clusives-A vehicle wheel comprising a hub indicated generally by reference numeral 2,

'a rim indicated generally by reference numeral 3, andv a corrugated web ordisk 4 joining the hub and rim. The hub piece 5 is illustratedv as the usual hub used in automobiles. It -is threaded at its outer end and is rovided with a hub cap 6. The innen end7 (the end next the vehicle) of the hula 5 has an outwardly extending iange? which forms a shoulder or abutment against which the inner edge of the disk 4 is clamped. As shown in Figures 2 and 4, this shoulder is provided with convolutions 8 which register with the corrugations in the disk 4. The

' disk 4 is clamped against the shoulder of the flange 7 by means of a follower 9, the inner end 'of which is flanged at 10 and bent into convolutions corresponding to the convolutions of the shoulder of the flange 7, and the corrugations of the disk 4. The follower 9 is pressed against the disk t0 clamp it against the hub shoulder by means of a ca 6, which is threaded so that the hub whee may be' demounted from the hub by unscrewing the cap 6, taking oli the follower 9 andpulling the wheel oil the hub. Another lwheel may then be placed on the hub, the

follower 9 replaced and the cap 6 screwed into place. The corrugations, as illustrated in the drawings, are radial corrugations extending from the hub to the periphery of the disk 4, where it joins the wheel rim, although thev disk may be otherwise corrugated within the broader scope of the invention. In the embodiment of the invention illustrated in Figures 1 to 6, inclusive,

the corrugations 11 of the disk 4 are of the same depth from the hub to the rim, the cor-A rugations, of course, being sharper at the smaller circumference around the'hub than they are at the'larger circumference at the,

outer edge of the disk next the rim. -As

shown in this modification, the corrugations do not extend to the extreme inner4 edge of the disk 4, but the extreme inner edge of the disk 4 reserves the uncorru'gated circular i) the disk, the corruations being pressed into lan initially dat dis This provides a straight circular inner edge for the disk 4. This inner edge can be more accuratel machined and makes a better centering lit over the hub than is the case oi a disk in which the corrugations extend to the exllO y treme inner edge of the disk. Moreover, in

this structure, the ange part of the hub may be made lighter and there is1 not the necessity of Yusing the filler piece as shown in the modification illustrated in Figures 7 to 12 in which the disk is corrugated to its extreme inner edge.

As shown in Figure 2, the straight inner edge of the disk fits over a tapered seat 25 which causes accurate centering. The outer edge of the disk is bent over at right angles and is Welded to the inner rim 26 of the rim. As shown in the drawings, the disk 4 joins thev rim along a serpentine line along the middle portion of the telly ring or rim 26. The line of junction between the disk and the inner rim 26 is preferably a little to the inner side of the middle rim and the bent over portion 27 extends toward the inner side of the Wheel. This permits asuicient space at one of the corrugations for the valve or filling tube of a pneumatic tire to extend through the inner rim 26. This valve is indicated in dotted lines at 28 in Figures 1, 2 and 3.

The corrugated disk 4 provides the requisite strength, particularly the necessary side stiness and resistance. The corrugations give the disk a side stiffness not obtainable in uncorrugated disks.. The metal or" the disk is made of a thicker'gauge at the hub portion to support the greater strains to which the metal is subjected. The disk is reduced or tapered to a thinner gauge at the edge where the area of the metal is greater and the metal is subjected to less strain. The tapered corrugated disk herein shown gives a maximum of strength with a minimum of weight.

A demountable outer or tire rim 3G is mounted on the inner rim 26. A. number of bolts 31 are welded at 32 to the inside of the inner rim 26. These bolts extend through holes cut in the edge of the disk 4 and are provided with hooklike ends 33, which engage the inner side of the inner rim 26. The other ends of' the bolts 31 are threaded at 34 to receive nuts 35.

The inner rim 26 has an inclined face 36 against which its a complementary face on the inside of the tire rim 30. The outer edge of the inner'rim 26 has an inclined face 37 opposite the inclined face 38 on the outer rim 30. A wedge ring 39 is arranged to fit in between these two faces to firmly clamp the two'rims together. Washers 40 are provided or the bolts 31. The washers 4Q have ears 41 'which fit against the wedge ring 39. The other edge of each washer has a right angle flange 42 which extends along, and at its end fits against the shank of the bolt 31. As shown in Figure 5, this flange 42 iscircular and extends somewhat less than 18) degrees around the bolt 31. lVhen the rim 30 1s to be demounted, the nuts 35 are loosened mensen and the washers 40 may then be turned to the left, as viewed inv Figure 5, so that the ears 4l. are turned away from the wedge ring k39 to permit its removal. The flange 42, since it extends part way only around the bolt, permits the washer to be turned. l/Vhen another tire rim is mounted and the wedge ring 39 is in place, the washers 40 are turned to the position shown in Figure 5, the flange 42 serving as a stop tohold the washers 40 in proper position and keep them from being turned beyond such position as the nuts 45 are tightened by being screwed in a right hand direction. This forms a simple and secure device for holding the demountable rim in place.

Referring to the modification shown in Figures 7 3 and 12z-The wheel comprises a hub 2, a rim 3 andv corrugated web or disk 4, the parts having the general arrangement shown in Figures 1v and 2. The hub 2 comprises a hub piece 5 shown as the usual hub piece for an automobile. Formed on the inner end of the hub piece 5 is a flange 50. This flange is flat on both sides and serves as a seat for a filler piece 51, which is corrugated to fit the corrugations of the disk 4. As shown in Figures 8 and 12, the filler piece 51 is substantially L-shaped in cross section having a vertical corrugated wall 52 and an annular wall 53 which ts against the flange 50. The bottoms of the corrugations in the wall 52 also abut against the flange 50 and are riveted thereto by rivets indicated by dotted lines vat 54. These rivets hold the filler piece 51 from 'rotation relative to the hub piece 5. The disk 4, as shown in its modification, has its corrugations extending to the extreme inner edge of the disk, the extreme inner edge of the disk fitting against the tapered seat 55 of the hub. The inner edge of the corrugated disk is machined to fit snugly over the tapered seat or barrel 55 of the hub to center the wheel. The central portion of the disk 4 is removable to clamp against the corrugated seat of the hub ortion which is formed by the corrugated ller block 51, by means of a runner-like follower 56 and the hub cap 57 threaded on the outer end 'of the hub piece 5. The follower 56 is a ring or sleeve which extends along the hub piece 5 and has an outwardly extending -back of the outer end of the follower 56.

This permits the hub cap to be dra-Wn up very tight to clamp the follower securely against the disk. As shown Figures 7, 8

and 12j. the eorrugations 4 are radial as in Figure 1, but are not ofthe same depth from erably pressed-out of a tapered blank, the

blank having a thicker gauge at the-center than at the periphery, so that the disk 4 will have the greater thickness at the hub where it is subject to the greatest strain. The outer edge of the disk which is turned over at right angles toward the inside (the Side 0f the wheel toward the vehicle) of the wheel is indicated at 59 and is secured thereto preferably by spot welding. The corrugations form of themselves the space at the outside of the disk for the valve stem of a pneumatic tire, such valve stem being indicated by dotted lines at 60.

In Figures 9, l() and l1 is illustrated a modification in which two filler pieces are employed for clamping the disk at the hub. The hub piece 5 has a fiat outwardly extending flange 50. Seated against this flange is a filler piece 70, which in turn forms the corrugated seat for the web or disk 4. As shown in this modification, the filler piece comprises a corrugated face 71 and outer and inner webs 72 and 73. the edges of which abut against the flange 50. The corrugated side 71 at the bottom of these corrugations fits against the flange 50 and is riveted thereto by rivets indicated at 74. A second filler piece 75 of substantially the same structure as the first filler piece, fits against the outer surface of the corrugated disk 4, the filler piece 75 having a face 76 and outer and inner lwebs 77 and 78 against the edges of which bears the iiange 79 of the follower 80. The follower 8O is forced against the hub by means of the hub cap 81 threaded on the outer end of the hub piece 5. The two filler pieces 70 and 75 have their exposed outer webs 72 and 77 of a smooth cylindrical form so that there are no exposed corrugations on the hub to gather dirt and the hub presents the appearance of a smooth round hub having the corrugated disk 4 projecting' from it.
